I olje- og/eller gassproduksjonsbrønner i undergrunnen krever transport av utstyr overveiende komplekse prosedyrer og transportsystemer Vanlige tilgjengelige systemer omfatter jevne wiresystemer, viklede rør, elektriske trekkmaskiner nede i brøn-nen og gjerinomstrømningslednings(TFL)systemer TFL anvender TFL stempler som pumpes opp og ned gjennom en produksjonsrør, som krever installasjon av parallelle produksjonsrør som er sammenkoplet nede i brønnen slik at fluid kan sirkuleres i mot-satte retninger Bruk av parallelle produksjonsrør er kostbart og reduserer mengden av olje og/eller gass som kan produseres via brønnen In oil and/or gas production wells in the underground, transportation of equipment requires mainly complex procedures and transport systems. Commonly available systems include smooth wire systems, coiled pipes, electric traction machines down the well and thread flow line (TFL) systems. TFL uses TFL pistons that are pumped up and down. through a production pipe, which requires the installation of parallel production pipes that are interconnected down the well so that fluid can be circulated in opposite directions. The use of parallel production pipes is expensive and reduces the amount of oil and/or gas that can be produced via the well
De andre tigjengelige systemer krever komplekst utstyr som er sammenkoplet med viklede rønnjektorer, eller kraftkabler eller wiretromler hvorfra rør, kraftkabler og/eller wirere som kan være opp til 10 km lange, blir spolet opp og ned via brønnhodet under transportaktivitetene nede i brønnen Et eksempel på en kjent trekkmaskin nede i brønnen som er forbundet med en kraft- og styreenhet på overflaten via en langstrakt kontrolledning er vist i internasjonal patentsøknad WO 93/18277, WO 91/16520, WO 90/02864 og WO 95/21987, og US patent 5 184 676 The other 10-way systems require complex equipment that is interconnected with coiled core injectors, or power cables or wire drums from which pipes, power cables and/or wires, which can be up to 10 km long, are coiled up and down via the wellhead during transport activities down in the well. An example of a known traction machine down in the well which is connected to a power and control unit on the surface via an elongated control line is shown in international patent application WO 93/18277, WO 91/16520, WO 90/02864 and WO 95/21987, and US patent 5 184,676

En plastisk nettangtrakt 34 som er forsynt med en oppdnftsnng 35 og vist i detalj på fig 6 blir derved vinsjet mot vannflaten 30 slik at en utstyrsmodul kan droppes ned i trakten 34 fra et fartøy 36 Modulen som dermed droppes vil gli gjennom det fleksible rør 8 inn i karusellhuset 5 og inn i karusellen 25 A plastic net hopper 34 which is provided with a riser 35 and shown in detail in Fig. 6 is thereby winched towards the water surface 30 so that an equipment module can be dropped into the hopper 34 from a vessel 36. The module which is thus dropped will slide through the flexible pipe 8 into in carousel house 5 and into carousel 25
Fig 7 viser hvordan et automatisk undervannskjøretøy (AUV) 40 koples til en utstyrsoverfønngsseksjon 41 på karusellhuset 5 AUV omfatter en utstyrsmodulbærer 42 som er i stand til å innsette og/eller fjerne utstyrsmoduler 43 inn i og/eller bort fra over-fønngsseksjonen 41 Overfønngsseksjonen omfatter en modultransportør 44 og modul-gnpearm 45 for overfønng av utstyrsmoduler mellom transportøren 44 og karusellen 28 Fig 7 shows how an automatic underwater vehicle (AUV) 40 is connected to an equipment transfer section 41 on the carousel housing 5 The AUV comprises an equipment module carrier 42 which is able to insert and/or remove equipment modules 43 into and/or away from the transfer section 41 The transfer section comprises a module conveyor 44 and module transfer arm 45 for transfer of equipment modules between the conveyor 44 and the carousel 28
Det vil være klart at utsettingskanalen 6 for skyttehnnretningen kan være beliggende nedenfor karusellhuset 5, og at brønnen kan være forsynt med et utstyrsgarasje nede i brønnen som er vist på fig 8 It will be clear that the launch channel 6 for the gunning direction can be located below the carousel housing 5, and that the well can be provided with an equipment garage down in the well, which is shown in fig 8
Fig 8 viser en brønn 50 gjennom hvilken en skyttehnnretmng 51 beveger seg i retning nedover Skyttehnnretningen 51 er forsynt med to hjul 52 som ruller på den indre overflate av brannrøret 53, og to svingbare TFL-paraplykonuser 54 og bærer en utstyrsmodul 55 TFL-paraplyen er fortnnnsvis for bruk ved anvendelser med store diametere, og den sylindriske TFL-tetning er fortnnnsvis for mindre rørseksjoner Dette muliggjør at det kan anvendes et verktøy med to tetningsfester for stor bredde av anvendelser Tilveie- Fig 8 shows a well 50 through which a shooting guide 51 moves in a downward direction. The shooting guide 51 is provided with two wheels 52 that roll on the inner surface of the fire tube 53, and two pivotable TFL umbrella cones 54 and carries an equipment module 55. The TFL umbrella is preferably for use in applications with large diameters, and the cylindrical TFL seal is preferably for smaller pipe sections. This enables a tool with two seal attachments to be used for a wide range of applications.
